Jeremy has a serious problem – he is too intelligent. His teachers are so convinced of his genius that they believe he should change schools to attend a special high-school for gifted an talented children !!! Our heroes are in a tight spot. Without Jeremy, they may as well give up the fight against X.A.N.A, and any hope of bringing Aelita to life. Jeremy has decided to fail all the tests he is going to be forced to sit on purpose. While he’s stuck in exams, X.A.N.A has transformed the school’s rat population into an army. How will our heroes overcome them without Jeremy ?

Detailed summary

In the city sewers, one of XANA’s spectres enters a rat. The rat becomes aggressive and attacks all the others nearby…each rat bitten falls under XANA’s control and an army is raised beneath the ground…

At the school, Jeremy worries: the psychologist has been monitoring him for a long time and wants him to take some tests to see if he really is gifted…the brainiac obviously isn’t the least bit interested in being sent to a special school…his place is at Kadic to fight XANA… Resigned, he meets the adult in the library while all the other students are in the cafeteria.

On Lyoko, Aelita hears pulsations, a Tower has been activated in the Desert…the army of rats is growing and begins to invade the school, squishing into every corner of the buildings…Aelita tries to warn Jeremy but he’s with the psychologist doing the test to determine his IQ…the brainiac is busy writing wrong answers…

The rats do not wait for a signal and go on the offensive; they bite through the electric wires, plunging Kadic into darkness, leaving no light except for the blood red of their possessed eyes! The rodents begin to approach the students, hissing and baring their fangs. The students gather in the cafeteria and fight the rats off using their trays. They escape the room by breaking a window and seek refuge on the roof of the science building, barricading the only door. But that doesn’t seem to stop the rats, which one by one gnaw on the door...

Jeremy and the psychologist are also assaulted, repelling the possessed rats with flashes of light… Ulrich, Odd and Yumi descend from the science building roof by using a fire hose and run to the factory…
The ubiquity of the rats is stifling and the Lyoko Warriors struggle to reach the abandoned factory.

Yumi virtualises her two comrades guided by Jeremy over the phone.
The battle begins in the Desert Sector with Krabes and XANA modifies the incline of the plateau…Odd is devirtualised, narrowly missing a fatal fall into the vast Digital Sea. Ulrich is in a bad place. Jeremy arrives from Kadic and sends Yumi for reinforcements…
Aelita is finally able to reach and enter the Tower. At the school, the psychologist and students hidden on the roof see the sharp fangs of the rats approaching inexorably…all are saved by the deactivation of the Tower and the Return to the Past.

To avoid being sent to a new school, Jeremy retakes the test, but this time is able to make all sorts of errors thanks to Odd giving him the answers…

Trivia

About the characters

- First appearances of the psychologist Hans Klotz, Rosa Petitjean and Christophe M’Bala.
- First episode in which Yumi virtualises her friends.
- Jeremy is gifted and struggles not to be sent to a special school more fitting to him; his parents wouldn’t miss the opportunity for him to have a big scholarship to a school for the gifted.

About errors

- How can Yumi communicate with Odd and Ulrich without the microphone?
- Just before the Krabe explodes, the leg Yumi cut off reappears.
- In one scene, the door barricaded by Jeremy and Mr Klotz isn’t there anymore!
- When Sissi enters her room, the handle of her door is on the right instead of the left.
- After Jeremy has communicated with Aelita and needs to call Yumi, it’s not his phone we see but Yumi’s.
- During the return to the past, the doors of the science building are open when they shouldn’t be, and the tree knocked down by the rats has disappeared.
- The psychologist tells Jeremy his name is Mr Simone, but according to official documents his name is Hans Klotz.
- Jim says that the science building is the only one without access to the sewers. In several episodes, the laboratory classrooms have sinks.
- Odd’s pants are entirely the one shade of purple when he watches Yumi (on her bike) ride through the rats, before Jim announces where they should hide, when he (Odd) and Ulrich fend off the rats in front of the science building and when he says “I’ll go.”
- During the battle, a platform is turned to a vertical position. At one point Aelita and Yumi are on a platform sticking out of it near the bottom. When the Krabes are defeated, they somehow manage to get to the tower and we don’t know how.

About the series

- French title: Enragés

- This form of attack is the same as in episode 12 “Swarming Attack”, episode 44 “Vertigo” episode 58 “The Pretender” and episode 74 “I’d Rather Not Talk About It”.
- First time XANA takes control of a living organism and changes the incline of a plateau in one of Lyoko’s Sectors.
- The activated tower is the same as in episode 4, “Log Book”.
- At the very end, when the psychologist is trapped inside by rats, he doesn’t have shoes; where did they go?

About references

- Yumi: “Game, set and match.”
This is the phrase used when a tennis match is won.

- Yumi (to Sissi): “Your carriage, Cinderella.”
She references the famous animated film by Walt Disney in which the young Cinderella is transformed by her fairy godmother into a beautiful princess.

- The puzzle the psychologist works on is none other than the well-known Rubik’s cube.

- Jeremy: “The shrinks decided that I have to take all kinds of tests tonight to determine what my IQ is.”
The Intelligence Quota or IQ is the result of psychological tests which can evaluate someone’s intelligence.

Quotes

Aelita: What’s a library, Jeremy?
Jeremy: A databank where everything’s printed on paper, and where you can’t make any noise!
Aelita: Oh, because I guess you need silence to concentrate on what you’re studying!
Jeremy (watching Odd and Ulrich playing with a ball of paper): Yes, and so as not to miss the match point!

Jim: Ah! Ok, well if that’s the way you wanna play, I can play just as hard as you can, my little friends! (he turns and grabs the principal’s ear) YYYYOU! Two hours detention! I’m...! Whoa, sorry about that, Sir, I uh...

Jeremy: If the tests show that I have a really high IQ, the guy is going to see to it that I get sent to another school...
Odd: Are you saying that he’s going to send you to a school for like, future Einsteins?

Yumi: That is serious! If you’re not here we can never go to Lyoko again, and XANA will be able to do what he wants!
Jeremy: It’s not just that, guys! I don’t want to leave here because of you all...you’re my friends...

Jeremy: The psychologist creep couldn’t wait to talk to my parents.

Odd: What’s the big problem? You mess up on the tests, and they’ll think you’re a big moron! Nobody’ll ever know!

Yumi: I virtualised you too far away from Aelita!
Odd: That’s ok, we could use a little exercise to get warmed up!

Ulrich: Your two knights in armour have come to protect you!

Jeremy: Anyway, I’ve got a foolproof way of flunking: I’m gonna get all of my answers from Odd!
(The others laugh)
Odd: Yeah, yeah, go on, laugh your heads off. But who knows, you might be in for a big surprise!
